Ryan's Mart was an open air market that auctioned African men, women and children in the mid 1800s. It's now a museum about South Carolina's shameful past. Text-heavy exhibits illuminate the slave experience; the few artifacts, such as leg shackles, are especially chilling. For first-hand stories, listen to the oral recollections of former slave Elijah Green and others.
Combination ticket with the Old Exchange is adult/child $15/8.
